Door closers, as the name indicates, are door hardware, which have been used for domestic as well as commercial purposes for quite some time. On slight observation, one notices as to what extent are these door closers used at homes, offices, malls, buildings, and schools etc.
The first use of door closer is to maintain privacy. Whether at office or at home, people need their privacy to be maintained, and it gets a bit irritating if your door is left open by people coming and going out of your room. So, in order to maintain privacy and to guarantee no external interferences, people opt for the use of door closers.
Door closers, being mechanical devices, work as an addition to the security of a home and a commercial building. Since they help in monitoring the entrance and exits of doors in an automatic way, many individuals are saved from the efforts as well as pestering that one faces in such facility provision. Hence, door closers surround one with safety as well as comfort. They are counted as an essential hardware from hardware market stores and online websites as well.
Door Closer are especially made for the main exit and entrance doors of buildings. As people constantly walk in and out, they let in a blast of air with every entry, even if there are door closers fixed to the doors. Without door closers, the blast of air coming in will be constant and will affect the air conditioning arrangements inside. The constant entry of outside air will increase the power bills.
Door closers exhibit their highly beneficial use in case of fire doors. In a place where fire may break on an unexpected note, the door closers on fire doors can help in suppressing any possibility of the flames spreading out in the entire building out of that one room. In fact, most of the material used for door closers is fire repellent. When it comes to security of a household, trespassers and even burglars can face a lot of difficulty in breaking in because of the strong hold of door closers joined with door frames, barred with various codes.
Door closers turn out to be quite long lasting. Since grade one closers tend to last for quite a long period, they are fixed to some good traffic areas and can handle entrance as well as exits at such areas for about 400 times a day. Grade two closers are meant for moderate traffic areas and are therefore used mostly in offices. They can only function for around 50 to 100 times per day.
Door closers may be surface mounted door closers or concealed closers. Concealed closers may be concealed overhead, hidden within the doors, or hidden on the floor. A surface mounted door closer is a small box that remains attached to the top of a door with a mechanical arm extending from the box to the doorframe. In the concealed prototypes, the box will be hidden, with only the arm being visible.
Nowadays, door closers are also available with “delayed action”. They help the doors to remain open for a preset period of time and after that time span ends, they start closing slowly. This is a special type of door closer that is available for those families who have an old member or someone who uses wheelchairs.
